Answer:

3 units

Step-by-step explanation:

The total circumference of the circle is 36 units, and the ratio of the length of the arc to the circumference of the circle is (pi/6)/2pi = 1/12. So, the length of the arc is 36*(1/12) = 3 units.

Property used in the equation 9+3+1

Tju [1.3M]

Answer:

That is the<u> associative property</u>. In addition, it doesn't matter what order you add things in, so you can "associate" any grouping of additions and get the same result:

(a+b)+c = a+(b+c)

Note that this is true for multiplication as well:

(a*b)*c = a*(b*c)

Suppose that you draw two cards from a deck. After drawing the first card, you do not put the first card back in the deck. What

S_A_V [24]

Answer:

(B) 0.0588

Step-by-step explanation:

The probability is calculated as a division between the number of possibilities that satisfy a condition and the number of total possibilities. Then, the probability that the first card is diamonds is:

$P_1=\frac{13}{52}$

Because the deck has 52 cards and 13 of them are diamonds.

Then, if the first card was diamonds, the probability that the second card is also diamond is:

$P_2=\frac{12}{51}$

Because now, we just have 51 cards and 12 of them are diamonds.

Therefore, the probability that both cards are diamonds is calculated as a multiplication between $P_1$ and $P_2$ . This is:

$P=\frac{13}{52}*\frac{12}{51}=\frac{1}{17}=0.0588$

What is the answer to a/9 =−4

frez [133]

Multiply all the terms by the same value to eliminate fraction denominators
a/9=-4
9 . a/9=9(-4)
The dot means multiplication
Then simplify to simplify cancel the multiplied terms that are in the denominator
a=9 . -4
Multiply the number
9 . -4 =36
And don’t forget to add the negative sign so the answer is
a= -36
